Is your feature request related to a problem? Please describe. Right now the game seems to be in practice mode, where you are able to see the time taken to finish that particular cube. That is good for beginners but it's boring.

Describe the solution you'd like I think there should be a way to find the highest score (if you assign score based on performance of the solver/player) or the least time taken and the count down should be in reverse, in comparision to the previous time taken.

Describe alternatives you've considered

• we can make a database and store all the details of the player
• Or we can use the local memory
